Heads of Families at the First Census of the United States Taken in the Year 1790: Pennsylvania Paperback - 2011

From the publisher

No other official record or group of records is as historically significant as the 1790 census of the United States. The original 1790 enumerations covered the present states of Connecticut, Delaware, Georgia, Kentucky, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, and Virginia. Unfortunately, not all the schedules have survived, the returns for the states of Delaware, Georgia, Kentucky, New Jersey, Tennessee, and Virginia having been lost or destroyed, possibly when the British burned the Capitol at Washington during the War of 1812, though there seems to be no proof for this. For Virginia, taxpayer lists made in the years 1782-1785 have been reconstructed as replacements for the original returns. In response to repeated requests from genealogists, historians, and patriotic societies, the surviving census records were published by the Bureau of the Census in 1907 and 1908. The twelve states whose records were then extant are each covered by a single volume. The twelve published volumes contain the names of the heads of about 400,000 families, with information concerning their place of residence, the size of their families, and the approximate ages of the male family members. The families, averaging six people each, comprised about 2,400,000 individuals, or approximately 75% of the total population of the United States at the time.
